U(VI) transport in subsurface materials: is two-site, one-species modeling sufficient?

Creator:: Harrington, Stephanie J.
Abstract:: Uranium adsorption to Hanford sediment was studied for various pH, total inorganic carbon concentrations, and total U(VI) concentrations. Both batch and transport studies were done in an attempt to understand the adsorptive trend of U(VI) on Hanford sediment, and the changes in adsorption as both pH and total inorganic carbon...

Numerical response of concrete-lined tunnels crossing active faults

Creator:: Lange, Stephanie
Abstract:: A challenge for municipal authorities of growing urban areas is to provide larger and faster transportation and utility networks that are safe and resilient to significant disruptions after an earthquake event and other disasters. Urban regions, like the San Francisco Bay or the Los Angeles area, are situated in seismically...

Modeling and Finite Element Analysis of a Standard Concrete Canoe

Creator:: Stache, Stephanie S.
Abstract:: This thesis project provides a guiding framework for the structural analysis portion of the National Concrete Canoe Competition (NCCC). Step-by-step instructions on how to 3-dimensionally model a “standard” sized concrete canoe in AutoCAD Civil 3D, import the model into SAP2000, and proceed to analyze the canoe with the SAP2000 finite...

Design and environmental performance of near-surface mounted carbon fiber reinforced polymer strips for shear strengthening reinforced concrete bridge girders

Creator:: Goebel, Jacob Hans
Abstract:: During the interstate expansion of the 1950s, many conventionally reinforced concrete deck girder bridges were built throughout the country. These now vintage bridges commonly exhibit diagonal cracking and rate inadequately for shear, thus they are candidates for shear strengthening to extend their useful life. Near-surface mounted (NSM) retrofitting is a...

Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

Creator:: Johnson, Brandon Ang
Abstract:: Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...

Root Cause Analysis of Transportation Infrastructure Accidents Using Fault Trees

Creator:: Yang, Rebecca
Abstract:: The Bureau of Labor Statistics cites construction as the most hazardous industry within the United States. The construction industry was responsible for 20% of all fatal occupational injuries in 2014. Approximately 20% of the construction injuries occur within Heavy Civil Engineering, in which there are 950,000 workers employed annually. This...

Understanding the Similarities and Differences Between Academia and the Engineering Workplace through Barriers to Adoption, Epistemic Beliefs, and Problem-Solving Behavior

Creator:: Gestson, Sean Lyle
Abstract:: Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...

Alkali-silica reaction in concrete containing recycled concrete aggregates

Creator:: Adams, Matthew P.
Abstract:: Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...

Assessing the Trade-Off Between Sustainability and Resiliency of Reinforced Concrete Alternatives in Corrosive Conditions: An LCA-System Dynamics Approach

Creator:: Moreno Rangel, Erick D.
Abstract:: Concrete has been categorized as a key contributor of CO2 (carbon) emissions into the atmosphere. This is mostly associated with the production of ordinary portland cement (OPC). The concrete and cement industries are pursuing a path to reduce their carbon emissions generally in accordance with the climate change goals outlined...

Exploring Civil Engineering Undergraduate and Practitioners’ Performance on Strength of Materials Concept Inventory

Creator:: Sanchez, Dominga
Abstract:: Preparing successful engineering undergraduate students for the workforce is imperative and requires students to apply their conceptual understanding of engineering fundamentals to engineering design work. Conceptual understanding is assessed through the use of concept inventories. Learning theories may help explain differences in concept inventory performance. Expert novice theory suggests that...
